Interesting test made by Venderbilt University showing that mental imagery dictates what you see later. Well, in my opinion the number of participants is a bit small (what actually mean more than 11 participants?). Article starts with:

"There's a big debate about what happens in our brain when we imagine visual items, like pictures, for example. Some people think our brains perceive visual images pictorially, using a part of the brain known for processing simple visual features.Other people think our brains perceive visual stimuli symbolically, using the region of the brain known for processing words and language."

Where is a photographer in this story? To project and present him self, wheather brains perceive visual immagery pictorially or prerceive visual stimuly symbolically (or is it both?). And where is viewer in this story? To implement him self, wheather perceiving visual immagery pictorial or perceiving visual stimuly symbolically (or is it both?).
